"double emphasis" bug when converting to asciidoc

[tx-pandoc]

(Creating bug report as suggested by John on pandoc-discuss on Tue, 04 Jan 2022 19:17:42 -0800)

Description
In some cases when doing HTML to asciidoc conversion with pandoc it creates wrongly "intraword emphasis" instead of simple "emphasis". (And this in turn seems to trigger also a bug in asciidoc when creating Docbook XML.)

Example:
<a href=x.htm><i>Xx</i></a><i>,</i>
... will be converted to...
link:x.htm[_Xx_]__,__

Versions used
pandoc 2.16.2 (macOS ports)
asciidoc 9.1.0

More details
I created a few test cases and collected the results in a simple CSV table.

Neither processor seems to parse this as a link.
I get:
